Setting options for protection parameters of parameter sets A and B
Parameter set A (standard)
The protection parameters of parameter set A can be set in different ways using the rotary
switches:
•
Manually on the rotary switch
•
On the display of the ETU600 electronic trip unit; the rotary switch must be set to the
"e.SET" position.
•
Via a communication connection; the rotary switch must be set to the "e.SET" position.
(1)
Positions of manually settable protection parameters
(2)
"e.SET" position
Parameter set B
A second parameter set is available as an option. The protection parameters for this
parameter set B can only be set on the display of the ETU600 electronic trip unit or via a
communication connection.
Protection parameter values in registers
The currently active protection parameter values for parameter set A can be read out of a
register. The protection parameter value corresponds to the set rotary switch position (1) or
the setting for the "e.SET" position (2).
The protection parameter values for the manual settings on the rotary switch can only be
read. The setting for the "e.SET" position (2) is located in an additional register and can be
both read and written.
The setting for parameter set B is located in an additional register and can be both read and
written. This register is only available if the second parameter set option has been ordered.
For more information on ordering function extensions, refer to Chapter "2.5 Function
packages" in the 3WA Equipment Manual (Page 5).
Depending on the protection parameter, additional parameters exist which can also occur
twice if the second parameter set is enabled.
